CLF-C02 By islever Editorial Last updated Oct 13, 2026

Define methods of deploying and operating in the AWS Cloud.

Short answer

AC AWS Cloud Development Kit (AWS CDK) supports TypeScript and Python among its first-class languages.

Question

Which programming languages does AWS Cloud Development Kit (AWS CDK) currently support? (Choose two.)

Python Correct Answer
Swift
TypeScript Correct Answer
Ruby
PHP

Key Takeaways

The question tests knowledge of AWS CDK's language ecosystem, with the common trap being confusion with other AWS SDKs or general cloud tools that might support different languages like Ruby or PHP.

This question addresses the programming languages supported by the AWS Cloud Development Kit (AWS CDK). It establishes that TypeScript and Python are among the officially supported first-class languages for infrastructure-as-code.

Common mistake: Learners often incorrectly select Ruby or PHP, assuming broader language support similar to older IaC tools or general-purpose cloud APIs, rather than knowing the specific first-class list.

Expert Analysis

Why the Answer Is Correct

The AWS Cloud Development Kit (AWS CDK) provides first-class support for TypeScript, JavaScript, Python, Java, C#/.NET, and Go. Therefore, selecting TypeScript (C) and Python (A) is correct as they are both primary languages for CDK development. The documentation explicitly lists these as the core supported environments.

Why the Other Options Are Wrong

Swift (B), Ruby (D), and PHP (E) are not currently supported by AWS CDK. While you can technically use the AWS CLI or SDKs in any language, CDK constructs are specifically built and typed for the supported set. Choosing these options reflects a misunderstanding of the tool's current capabilities.

Community Comment Notes
